Two gears 431 rotate, thus, final to drive magnet 44 to rotate.
In above-mentioned hand operation, particular location detection process is as follows：Power transmission shaft 42 will after the speed change of reduction gear box 43
Power is transferred to the magnet 44 on the output shaft of reduction gear box 43, it is assumed that the load (such as solar protection devices) of tube shaped electric machine is from up stroke
Point (down stroke point), which is moved in the total kilometres of down stroke point (up stroke point), needs the rotation m circles of power transmission shaft 42, and reduction gearing
Case 43 makes power transmission shaft 42 with the gearratio that magnet 44 rotates be n：1, and m≤n, now absolute displacement transducer 47 can enter line position
Detection is put, as long as the number of turns≤1 that the stroke of i.e. load is only capable of causing magnet 44 to rotate is enclosed, with regard to position detection can be carried out, if load
Stroke the number of turns ＞ 1 that magnet 44 rotates is enclosed, then the None- identified position of absolute displacement transducer 47.Can be by reducing gear
Increase the planetary gear of corresponding series in roller box 43 to change gearratio of the power transmission shaft 42 with magnet 44, it is ensured that what magnet 44 rotated
The number of turns≤1 is enclosed, naturally it is also possible to which the number of turns≤1 for using other modes that magnet is rotated is enclosed.
Absolute displacement transducer 47 is not worked when powering off, and the position signalling that magnet 44 rotates is gathered before power-off, works as pipe
When shape motor is once again powered up the magnetic field for the magnet 44 that absolute displacement transducer 47 collects changes, and is collected by above-mentioned
Magnetic field variation signal is now loaded residing particular location.
Referring to Fig. 5, the control circuit on control circuit board 5 includes power module 51, control module 52, commutation control module
53rd, motor drive module 54, signal processing module 55.The input of power module 51 is connected to the AC power of outside, and defeated
Go out end to be then connected with control module 52 and commutation control module 53, powered for control module 52 and commutation control module 53.Control
The output end of module 2 is connected to the input of commutation control module 53, and the output end of commutation control module 53 is connected to motor drive
The input of dynamic model block 54, so as to the operating of motor.
Above-mentioned magnet 44 and absolute displacement transducer 47 form signal detection module, the input of signal processing module 55
The output end of signal detection module, i.e. absolute displacement transducer 47 are connected to, the output end of signal processing module 55 is then connected to
The input of control module 52.Led between signal processing module 55 and absolute displacement transducer 47 by SPI communication interface
Letter, and then communicated between signal processing module 55 and control module 52 by serial ports.
After signal processing module 55 receives the magnetic field variation signal that absolute displacement transducer 47 collects, the magnetic field is become
Control module 52 is sent to after changing signal transacting, magnet 44 is calculated according to the magnetic field variation signal received in control module 52
The angle change of rotation, so as to judge the number of turns of motor rotation, it follows that the now residing particular location of load.
Embodiment two
Referring to Fig. 6 and Fig. 7, in the present embodiment, it is with the difference of above-described embodiment one, above-mentioned position detection machine
